There was a skunk living under our shed when I was a kid (maybe 14 yrs old). There was 2 holes burrowed under the shed on opposite sides. I ran the hose in one hole and stood back 30 yds and watched the exit hole with my 10/22. I was expecting to shoot one, but I ended up shooting 3 of them, a mother and two young ones.
I don't know if this would apply to the skunks under your cabin or not, but if it does it's fast and effective..
